Battle of Britain Day 63. Cloudy, rainy weather returns after days of good flying weather and restricts Luftwaffe to mainly reconnaissance raids in the afternoon. 6 small raids approach London at 5.15 PM, presumably to drop incendiaries as markers, but these are turned back by RAF fighters (2 Dornier bombers shot down). 1 Spitfire is lost in combat (2 more fighters destroyed and 3 damaged in training operations). Overnight, East End of London is again bombed, as well as South Wales, West Midlands and Liverpool.
Royal Navy controls the Straits of Gibraltar; Vichy government has agreed to notify them to ensure safe passage of French ships. At 6 PM, French admiralty informs British Naval Attaché in Madrid that 3 cruisers intend to sail through the Straits next day. Despite this and other warnings, Royal Navy fails to appreciate the significance to the impending Free French landings at Dakar.
